If you are using font awesome icons, then you can use this:
To import font-awesome:
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
Usage:
Current Price: <i class="fa fa-inr"></i> 400.00
will show as:
From what i understand, you don't wanna remove it, nor hide it ? Because you might wanna reuse it later ..but don't want it to have the old content if ever you open it up again ?
<div class="modal hide fade">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3>Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<a href="#" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div>
If you wanna use it as a dynamic template just do something like
$(selector).modal({show: true})
....
$(selector).modal({show: false})
$(".modal-body").empty()
....
$(".modal-body").append("new stuff & text")
$(selector).modal({show: true})

tosh's answer gets to the heart of the question nicely. Here's some additional information....
ng-bind
and ng-model
both have the concept of transforming data before outputting it for the user. To that end, ng-bind
uses filters, while ng-model
uses formatters.
With ng-bind
, you can use a filter to transform your data. For example,
<div ng-bind="mystring | uppercase"></div>
,
or more simply:
<div>{{mystring | uppercase}}</div>
Note that uppercase
is a built-in angular filter, although you can also build your own filter.
To create an ng-model formatter, you create a directive that does require: 'ngModel'
, which allows that directive to gain access to ngModel's controller
. For example:
app.directive('myModelFormatter', function() {
return {
require: 'ngModel',
link: function(scope, element, attrs, controller) {
controller.$formatters.push(function(value) {
return value.toUpperCase();
});
}
}
}
Then in your partial:
<input ngModel="mystring" my-model-formatter />
This is essentially the ng-model
equivalent of what the uppercase
filter is doing in the ng-bind
example above.
Now, what if you plan to allow the user to change the value of mystring
? ng-bind
only has one way binding, from model-->view. However, ng-model
can bind from view-->model which means that you may allow the user to change the model's data, and using a parser you can format the user's data in a streamlined manner. Here's what that looks like:
app.directive('myModelFormatter', function() {
return {
require: 'ngModel',
link: function(scope, element, attrs, controller) {
controller.$parsers.push(function(value) {
return value.toLowerCase();
});
}
}
}
Play with a live plunker of the ng-model
formatter/parser examples
ng-model
also has built-in validation. Simply modify your $parsers
or $formatters
function to call ngModel's controller.$setValidity(validationErrorKey, isValid)
function.
Angular 1.3 has a new $validators array which you can use for validation instead of $parsers
or $formatters
.
This allows you to type on every line simultaneously.
I found the solution above here.
I think this is much easier than using regex.
I have done quite a bit of what you're talking about, and SOAP interoperability between platforms has one cardinal rule: CONTRACT FIRST. Do not derive your WSDL from code and then try to generate a client on a different platform. Anything more than "Hello World" type functions will very likely fail to generate code, fail to talk at runtime or (my favorite) fail to properly send or receive all of the data without raising an error.
That said, WSDL is complicated, nasty stuff and I avoid writing it from scratch whenever possible. Here are some guidelines for reliable interop of services (using Web References, WCF, Axis2/Java, WS02, Ruby, Python, whatever):

dict.copy() is a shallow copy function for dictionary
id is built-in function that gives you the address of variable
First you need to understand "why is this particular problem is happening?"
In [1]: my_dict = {'a': [1, 2, 3], 'b': [4, 5, 6]}
In [2]: my_copy = my_dict.copy()
In [3]: id(my_dict)
Out[3]: 140190444167808
In [4]: id(my_copy)
Out[4]: 140190444170328
In [5]: id(my_copy['a'])
Out[5]: 140190444024104
In [6]: id(my_dict['a'])
Out[6]: 140190444024104
The address of the list present in both the dicts for key 'a' is pointing to same location.
Therefore when you change value of the list in my_dict, the list in my_copy changes as well.
Solution for data structure mentioned in the question:
In [7]: my_copy = {key: value[:] for key, value in my_dict.items()}
In [8]: id(my_copy['a'])
Out[8]: 140190444024176
Or you can use deepcopy as mentioned above.
With versions of cut
I know of, no, this is not possible. cut
is primarily useful for parsing files where the separator is not whitespace (for example /etc/passwd
) and that have a fixed number of fields. Two separators in a row mean an empty field, and that goes for whitespace too.
Cannot open backup device 'c:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS\MSSQL\Backup\ C:\HostingSpaces\dbname_jun14_2010_new.bak'
The error is quite self-explanatory. The file C:\program files\...\Backup \c:\Hosting...\
is incorrectly formatted. This is quite obvious if you inspect the file name. Perhaps ommit the extra space in your backup statement?
BACKUP DATABASE go4sharepoint_1384_8481
TO DISK='C:\HostingSpaces\dbname_jun14_2010_new.bak' with FORMAT
Note there is no space between '

Its also possible to just create a matplotlib figure
object and then use plt.savefig(...)
:
from matplotlib import pyplot as plt
import seaborn as sns
import pandas as pd
df = sns.load_dataset('iris')
plt.figure() # Push new figure on stack
sns_plot = sns.pairplot(df, hue='species', size=2.5)
plt.savefig('output.png') # Save that figure
The Unconstrained Melody library is no longer maintained; Support was dropped in favour of Enums.NET.
In Enums.NET you'd use:
string description = ((MyEnum)value).AsString(EnumFormat.Description);
I implemented this in a generic, type-safe way in Unconstrained Melody - you'd use:
string description = Enums.GetDescription((MyEnum)value);
This:
I realise the core answer was just the cast from an int
to MyEnum
, but if you're doing a lot of enum work it's worth thinking about using Unconstrained Melody :)
Her is another R base
approach:
From your example: Some date:
Some_date<-"01/01/1979"
We tell R, "That is a Date"
Some_date<-as.Date(Some_date)
We extract the month:
months(Some_date)
output: [1] "January"
Finally, we can convert it to a numerical variable:
as.numeric(as.factor(months(Some_date)))
outpt: [1] 1
To disable next line:
// eslint-disable-next-line no-use-before-define
var thing = new Thing();
Or use the single line syntax:
var thing = new Thing(); // eslint-disable-line no-use-before-define
See the eslint docs
Jonathan from the ExcelCentral forums suggests:
=WEEKNUM(A1,2)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),2)+1
This formula extracts the week of the year [...] and then subtracts it from the week of the first day in the month to get the week of the month. You can change the day that weeks begin by changing the second argument of both WEEKNUM functions (set to 2 [for Monday] in the above example). For weeks beginning on Sunday, use:
=WEEKNUM(A1,1)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),1)+1
For weeks beginning on Tuesday, use:
=WEEKNUM(A1,12)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),12)+1
etc.
I like it better because it's using the built in week calculation functionality of Excel (WEEKNUM).
What about using something like:
<?php
$page_title = "Your page tile";
include("navigation.php"); // if required
echo("<title>$page_title</title>");
?>
PHP evaluates an empty string to false, so you can simply use:
if (trim($userinput['phoneNumber'])) {
// validate the phone number
} else {
echo "Phone number not entered<br/>";
}
If everything else fails, it's good to try my option and download a HAXM installer.
It needs to be copied to HAXM installation folder and then started from command line (start CMD as an Administrator). After restarting computer HAXM will be installed. It perfectly worked for me as I was having problems with installing it on my laptop.
After all simply type sc query
intelhaxm in your cmd in order to check whether HAXM is installed properly.
I was facing the same problem because some of the images are grey scale images in my data set, so i solve my problem by doing this
from PIL import Image
img = Image.open('my_image.jpg').convert('RGB')
# a line from my program
positive_images_array = np.array([np.array(Image.open(img).convert('RGB').resize((150, 150), Image.ANTIALIAS)) for img in images_in_yes_directory])
As an addition, consider that, as for read-only purposes the use of both is identical, you can access a char by indexing either with []
or *(<var> + <index>)
format:
printf("%c", x[1]); //Prints r
And:
printf("%c", *(x + 1)); //Prints r
Obviously, if you attempt to do
*(x + 1) = 'a';
You will probably get a Segmentation Fault, as you are trying to access read-only memory.

I was able to get this somewhat working for C++ static_assert()
. The wrinkle here is that static_assert()
only accepts string literals; constexpr string_view
will not work. You will need to accept extra text around the typename, but it works:
template<typename T>
constexpr void assertIfTestFailed()
{
#ifdef __clang__
static_assert(testFn<T>(), "Test failed on this used type: " __PRETTY_FUNCTION__);
#elif defined(__GNUC__)
static_assert(testFn<T>(), "Test failed on this used type: " __PRETTY_FUNCTION__);
#elif defined(_MSC_VER)
static_assert(testFn<T>(), "Test failed on this used type: " __FUNCSIG__);
#else
static_assert(testFn<T>(), "Test failed on this used type (see surrounding logged error for details).");
#endif
}
}
MSVC Output:

I dont know any reason why it shouldn't be possible.
Update: This function only avoids copy if it can, hence this is not the correct answer for this question. unutbu's answer is the right one.
a = a.astype(numpy.float32, copy=False)
numpy astype has a copy flag. Why shouldn't we use it ?

http://en.wikipedia.org/wiki/String_interning
string interning is a method of storing only one copy of each distinct string value, which must be immutable. Interning strings makes some string processing tasks more time- or space-efficient at the cost of requiring more time when the string is created or interned. The distinct values are stored in a string intern pool.
In my case, it was because the fixed element was being shown by using an animation. As stated in this link:
in Safari 9.1, having a position:fixed-element inside an animated element, may cause the position:fixed-element to not appear.
You should to use: ConfigurableApplicationContext instead of for ApplicationContext
You can also set a global ignore pattern in SVN's configuration file.
If MongoDB and RabbitMQ are running on the Host, then the port should already exposed as it is not within Docker.
You do not need the -p
option in order to expose ports from container to host. By default, all port are exposed. The -p
option allows you to expose a port from the container to the outside of the host.
So, my guess is that you do not need -p
at all and it should be working fine :)

According to my interpretation of the implementation of unicode-escape
and the unicode repr
in the CPython 2.6.5 source, yes; the only difference between repr(unicode_string)
and unicode_string.encode('unicode-escape')
is the inclusion of wrapping quotes and escaping whichever quote was used.
They are both driven by the same function, unicodeescape_string
. This function takes a parameter whose sole function is to toggle the addition of the wrapping quotes and escaping of that quote.
Enhanced Java 8+ example (Forked from Nikita Koksharov's answer)
public static void pack(String sourceDirPath, String zipFilePath) throws IOException {
Path p = Files.createFile(Paths.get(zipFilePath));
Path pp = Paths.get(sourceDirPath);
try (ZipOutputStream zs = new ZipOutputStream(Files.newOutputStream(p));
Stream<Path> paths = Files.walk(pp)) {
paths
.filter(path -> !Files.isDirectory(path))
.forEach(path -> {
ZipEntry zipEntry = new ZipEntry(pp.relativize(path).toString());
try {
zs.putNextEntry(zipEntry);
Files.copy(path, zs);
zs.closeEntry();
} catch (IOException e) {
System.err.println(e);
}
});
}
}
Files.walk
has been wrapped in try with resources
block so that stream can be closed. This resolves blocker issue identified by SonarQube

I use this function over result of my RPC services (via aspects) and it cleans recursively all result objects from proxies (if they are not initialized).
So, what's wrong with checking each element iteratively?
function arraysEqual(arr1, arr2) {
if(arr1.length !== arr2.length)
return false;
for(var i = arr1.length; i--;) {
if(arr1[i] !== arr2[i])
return false;
}
return true;
}
This is working Oracle example but it should work in MySQL too.

Some limited flexibility is available if your using the Afterglow Theme.
https://github.com/YabataDesign/afterglow-theme
You can edit your user preferences in the following way.
Sublime Text -> Preferences -> Settings - User:
{
"sidebar_size_14": true
}
https://github.com/YabataDesign/afterglow-theme#sidebar-size-options
Here is a simple regex which will remove the url("
and ")
from the returned string.
var css = $("#myElem").css("background-image");
var img = css.replace(/(?:^url\(["']?|["']?\)$)/g, "");
Just
$("#your_item").trigger("click");
using .trigger() you can simulate many type of events, just passing it as the parameter.
bool isFirst = compareString.Contains(firstString);
bool isSecond = compareString.Contains(secondString );
You can also create an extension:
var strArray = "Hello, playground".Letterize()
extension String {
func Letterize() -> [String] {
return map(self) { String($0) }
}
}
There was a relevant answer from Ask Tom published in April 2016.
If you have sufficient server power, you can do
select /*+ parallel */ count(*) from sometable
If you are just after an approximation, you can do :
select 5 * count(*) from sometable sample block (10);
Also, if there is
- a column that contains no nulls, but is not defined as NOT NULL, and
- there is an index on that column
you could try:
select /*+ index_ffs(t) */ count(*) from sometable t where indexed_col is not null
See the first answer to Accessing a matrix element in the "Mat" object (not the CvMat object) in OpenCV C++
Then just loop over all the elements in cout << M.at<double>(0,0);
rather than just 0,0
Or better still with the C++ interface:
cv::Mat M;
cout << "M = " << endl << " " << M << endl << endl;

I was trying to up the limit Wordpress sets on media uploads. I followed advice from some blog I’m not going to mention to raise the limit from 64MB to 2GB.
I did the following:
Created a (php.ini) file in WP ADMIN with the following integers:
upload_max_filesize = 2000MB
post_max_size = 2100MV
memory_limit = 2300MB
I immediately received this error when trying to log into my Wordpress dashboard to check if it worked:
“Allowed memory size of 262144 bytes exhausted (tried to allocate 24576 bytes)"
The above information in this chain helped me tremendously. (Stack usually does BTW)
I modified the PHP.ini file to the following:
upload_max_filesize = 2000M
post_max_size = 2100M
memory_limit = 536870912M
The major difference was only use M, not MB, and set that memory limit high.
As soon as I saved the changed the PHP.ini file, I saved it, went to login again and the login screen reappeared.
I went in and checked media uploads, ands bang:
I haven't restarted Apache yet… but all looks good.
Thanks everyone.
To run rake tasks with traditional arguments style:
rake task arg1 arg2
And then use:
task :task do |_, args|
puts "This is argument 1: #{args.first}"
end

alias origin_top_level top_level
def top_level
@top_level_tasks = [top_level_tasks.join(' ')]
origin_top_level
end
def parse_task_string(string) # :nodoc:

EXPECT
is a great program to use.
On Ubuntu install it with:
sudo apt-get install expect
On a CentOS Machine install it with:
yum install expect
Lets say you want to make a connection to a sftp server and then upload a local file from your local machine to the remote sftp server
#!/usr/bin/expect
spawn sftp [email protected]
expect "password:"
send "yourpasswordhere\n"
expect "sftp>"
send "cd logdirectory\n"
expect "sftp>"
send "put /var/log/file.log\n"
expect "sftp>"
send "exit\n"
interact
This opens a sftp connection with your password to the server.
Then it goes to the directory where you want to upload your file, in this case "logdirectory"
This uploads a log file from the local directory found at /var/log/ with the files name being file.log to the "logdirectory" on the remote server
Use ngModelChange
by breaking up the [(x)]
syntax into its two pieces, i.e., property databinding and event binding:
<input type="text" [ngModel]="mymodel" (ngModelChange)="valuechange($event)" />
{{mymodel}}
valuechange(newValue) {
mymodel = newValue;
console.log(newValue)
}
It works for the backspace key too.
You can delete a Node.js module manually. For Windows,
Go to the node_modules
directory of your repository.
Delete the Node.js module you don't want.
Don't forget to remove the reference to the module in your package.json file! Your project may still run with the reference, but you may get an error. You also don't want to leave unused references in your package.json file that can cause confusion later.
Follow the following steps if you are using proxy server:
Hope this helps.
A safer way to approach breaking a foreach
or while
loop in PHP is to nest an incrementing counter variable and if
conditional inside of the original loop. This gives you tighter control than break;
which can cause havoc elsewhere on a complicated page.
Example:
// Setup a counter
$ImageCounter = 0;
// Increment through repeater fields
while ( condition ):
$ImageCounter++;
// Only print the first while instance
if ($ImageCounter == 1) {
echo 'It worked just once';
}
// Close while statement
endwhile;
A really simple implementation is:
out = "".join(c for c in asking if c not in ('!','.',':'))
and keep adding any other types of punctuation.
A more efficient way would be
import string
stringIn = "string.with.punctuation!"
out = stringIn.translate(stringIn.maketrans("",""), string.punctuation)
Edit: There is some more discussion on efficiency and other implementations here: Best way to strip punctuation from a string in Python
You can't mix tab and spaces for identation. Best practice is to convert all tabs to spaces.
How to fix this? Well just delete all the spaces/tabs before each line and convert them uniformly either to tabs OR spaces, but don't mix. Best solution: enable in your Editor the option to convert automagically any tabs to spaces.
Also be aware that your actual problem may lie in the lines before this block, and python throws the error here, because of a leading invalid indentation which doesn't match the following identations!
System variables usually require a restart to become effective. Does it still not work after a restart?
You can get the traceback using a logger, at any level (DEBUG, INFO, ...). Note that using logging.exception
, the level is ERROR.
# test_app.py
import sys
import logging
logging.basicConfig(level="DEBUG")
def do_something():
raise ValueError(":(")
try:
do_something()
except Exception:
logging.debug("Something went wrong", exc_info=sys.exc_info())
DEBUG:root:Something went wrong
Traceback (most recent call last):
File "test_app.py", line 10, in <module>
do_something()
File "test_app.py", line 7, in do_something
raise ValueError(":(")
ValueError: :(
EDIT:
This works too (using python 3.6)
logging.debug("Something went wrong", exc_info=True)
Well, I am quite surprised that the alternatives to this syntax have not been mentioned. Another common (but older) mechanism is to call a function that isn't defined and rely on the optimizer to compile-out the function call if your assertion is correct.
#define MY_COMPILETIME_ASSERT(test) \
do { \
extern void you_did_something_bad(void); \
if (!(test)) \
you_did_something_bad(void); \
} while (0)
While this mechanism works (as long as optimizations are enabled) it has the downside of not reporting an error until you link, at which time it fails to find the definition for the function you_did_something_bad(). That's why kernel developers starting using tricks like the negative sized bit-field widths and the negative-sized arrays (the later of which stopped breaking builds in GCC 4.4).
In sympathy for the need for compile-time assertions, GCC 4.3 introduced the error
function attribute that allows you to extend upon this older concept, but generate a compile-time error with a message of your choosing -- no more cryptic "negative sized array" error messages!
#define MAKE_SURE_THIS_IS_FIVE(number) \
do { \
extern void this_isnt_five(void) __attribute__((error( \
"I asked for five and you gave me " #number))); \
if ((number) != 5) \
this_isnt_five(); \
} while (0)
In fact, as of Linux 3.9, we now have a macro called compiletime_assert
which uses this feature and most of the macros in bug.h
have been updated accordingly. Still, this macro can't be used as an initializer. However, using by statement expressions (another GCC C-extension), you can!
#define ANY_NUMBER_BUT_FIVE(number) \
({ \
typeof(number) n = (number); \
extern void this_number_is_five(void) __attribute__(( \
error("I told you not to give me a five!"))); \
if (n == 5) \
this_number_is_five(); \

This macro will evaluate its parameter exactly once (in case it has side-effects) and create a compile-time error that says "I told you not to give me a five!" if the expression evaluates to five or is not a compile-time constant.
So why aren't we using this instead of negative-sized bit-fields? Alas, there are currently many restrictions of the use of statement expressions, including their use as constant initializers (for enum constants, bit-field width, etc.) even if the statement expression is completely constant its self (i.e., can be fully evaluated at compile-time and otherwise passes the __builtin_constant_p()
test). Further, they cannot be used outside of a function body.
Hopefully, GCC will amend these shortcomings soon and allow constant statement expressions to be used as constant initializers. The challenge here is the language specification defining what is a legal constant expression. C++11 added the constexpr keyword for just this type or thing, but no counterpart exists in C11. While C11 did get static assertions, which will solve part of this problem, it wont solve all of these shortcomings. So I hope that gcc can make a constexpr functionality available as an extension via -std=gnuc99 & -std=gnuc11 or some such and allow its use on statement expressions et. al.
You can also export the database and then use a program like notepad++ to replace words and then inmport aigain.
Complete code with error handling and added file stream closes. Add it to your class that you want to be able to serialize and deserialize. In my case the class name is CreateResumeForm
. You should change it to your own class name. Android
interface Serializable
is not sufficient to save your objects to the file, it only creates streams.
// Constant with a file name
public static String fileName = "createResumeForm.ser";
// Serializes an object and saves it to a file
public void saveToFile(Context context) {
try {
FileOutputStream fileOutputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);
objectOutputStream.writeObject(this);
objectOutputStream.close();
fileOutputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
// Creates an object by reading it from a file
public static CreateResumeForm readFromFile(Context context) {
CreateResumeForm createResumeForm = null;
try {
FileInputStream fileInputStream = context.openFileInput(fileName);
ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
createResumeForm = (CreateResumeForm) objectInputStream.readObject();
objectInputStream.close();
fileInputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
catch (ClassNotFoundException e) {
e.printStackTrace();
}
return createResumeForm;
}
Use it like this in your Activity
:
form = CreateResumeForm.readFromFile(this);
In .NET 5, a new class has been introduced called JsonContent
, which derives from HttpContent
. See in Microsoft docs
This class has a static method called Create()
, which takes an object as a parameter.
Usage:
var myObject = new
{
foo = "Hello",
bar = "World",
};
JsonContent content = JsonContent.Create(myObject);
HttpResponseMessage response = await _httpClient.PostAsync("https://...", content);
Maybe placing the jquery.ui.widget.js
as second after jquery.ui.core.js

Get rid of the notion of vector entirely
template< typename IT, typename VT>
int index_of(IT begin, IT end, const VT& val)
{
int index = 0;
for (; begin != end; ++begin)
{
if (*begin == val) return index;
}
return -1;
}
This will allow you more flexibility and let you use constructs like
int squid[] = {5,2,7,4,1,6,3,0};
int sponge[] = {4,2,4,2,4,6,2,6};
int squidlen = sizeof(squid)/sizeof(squid[0]);
int position = index_of(&squid[0], &squid[squidlen], 3);
if (position >= 0) { std::cout << sponge[position] << std::endl; }
You could also search any other container sequentially as well.
To reset your form after submitting, you can just simply invoke this.form.reset()

I was working with EasyRepro, and when I debugged my code it was clicking on the element which is visible and enabled, and not navigating as expected. But finally I understood the root cause for the issue.
My Chrome was zoomed out 90%
Once i reset the zoom level, it clicked on the correct element and successfully navigated to next page.
if you've got this error by using the express generator, I've solved it by using
express --view=ejs myapp

express --view=pug myapp

First of all, Thank you DTing for awesome answer. It's pretty much perfect.
For those who are suffering from not having GCC access in shared hosting, Go for ActivePython instead of normal python like Scott Stafford mentioned. Here are the commands for that.
wget http://downloads.activestate.com/ActivePython/releases/2.7.13.2713/ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785.tar.gz
tar -zxvf ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785.tar.gz
cd ActivePython-2.7.13.2713-linux-x86_64-glibc-2.3.6-401785
./install.sh
It will ask you path to python directory. Enter
../../.localpython
Just replace above as Step 1 in DTing's answer and go ahead with Step 2 after that. Please note that ActivePython package URL may change with new release. You can always get new URL from here : http://www.activestate.com/activepython/downloads
Based on URL you need to change the name of tar and cd command based on file received.
See this thread https://github.com/ivaynberg/select2/issues/489, you can hide the search box by setting minimumResultsForSearch to a negative value.
$('select').select2({
minimumResultsForSearch: -1
});
try
date.innerHTML= date.innerHTML.replace(/^(..)\//,'<span>$1</span></br>')
_x000D_
<div id="date">23/05/2013</div>
_x000D_
Or you can always map
over an iterator, without the need to build an intermediate list:
>>> _ = map(sys.stdout.write, (x for x in string.letters if x in (y for y in "BigMan on campus")))
acgimnopsuBM
When you assign a variable (x = ...
), you are creating a variable in the current scope (e.g. local to the current function). If it happens to shadow a variable fron an outer (e.g. global) scope, well too bad - Python doesn't care (and that's a good thing). So you can't do this:
x = 0
def f():
x = 1
f()
print x #=>0
and expect 1
. Instead, you need do declare that you intend to use the global x
:
x = 0
def f():
global x
x = 1
f()
print x #=>1
But note that assignment of a variable is very different from method calls. You can always call methods on anything in scope - e.g. on variables that come from an outer (e.g. the global) scope because nothing local shadows them.
Also very important: Member assignment (x.name = ...
), item assignment (collection[key] = ...
), slice assignment (sliceable[start:end] = ...
) and propably more are all method calls as well! And therefore you don't need global
to change a global's members or call it methods (even when they mutate the object).
The python function returning just the package version in a machine-readable format:
from importlib.metadata import version
version('numpy')
Prior to python 3.8:
pip install importlib-metadata
from importlib_metadata import version
version('numpy')
The bash equivalent (here also invoked from python) would be much more complex (but more robust - see caution below):
import subprocess
def get_installed_ver(pkg_name):
bash_str="pip freeze | grep -w %s= | awk -F '==' {'print $2'} | tr -d '\n'" %(pkg_name)
return(subprocess.check_output(bash_str, shell=True).decode())
Sample usage:
# pkg_name="xgboost"
# pkg_name="Flask"
# pkg_name="Flask-Caching"
pkg_name="scikit-learn"
print(get_installed_ver(pkg_name))
>>> 0.22
Note that in both cases pkg_name
parameter should contain package name in the format as returned by pip freeze
and not as used during import
, e.g. scikit-learn
not sklearn
or Flask-Caching
, not flask_caching
.
Note that while invoking pip freeze
in bash version may seem inefficient, only this method proves to be sufficiently robust to package naming peculiarities and inconsistencies (e.g. underscores vs dashes, small vs large caps, and abbreviations such as sklearn
vs scikit-learn
).
Caution: in complex environments both variants can return surprise version numbers, inconsistent with what you can actually get during import
.
One such problem arises when there are other versions of the package hidden in a user site-packages
subfolder. As an illustration of the perils of using version()
here's a situation I encountered:
$ pip freeze | grep lightgbm
lightgbm==2.3.1
and
$ python -c "import lightgbm; print(lightgbm.__version__)"
2.3.1
vs.
$ python -c "from importlib_metadata import version; print(version(\"lightgbm\"))"
2.2.3
until you delete the subfolder with the old version (here 2.2.3) from the user folder (only one would normally be preserved by `pip` - the one installed as last with the `--user` switch):
$ ls /home/jovyan/.local/lib/python3.7/site-packages/lightgbm*
/home/jovyan/.local/lib/python3.7/site-packages/lightgbm-2.2.3.dist-info
/home/jovyan/.local/lib/python3.7/site-packages/lightgbm-2.3.1.dist-info
Another problem is having some conda-installed packages in the same environment. If they share dependencies with your pip-installed packages, and versions of these dependencies differ, you may get downgrades of your pip-installed dependencies.
To illustrate, the latest version of numpy
available in PyPI on 04-01-2020 was 1.18.0, while at the same time Anaconda's conda-forge
channel had only 1.17.3 version on numpy
as their latest. So when you installed a basemap
package with conda (as second), your previously pip-installed numpy
would get downgraded by conda to 1.17.3, and version 1.18.0 would become unavailable to the import
function. In this case version()
would be right, and pip freeze
/conda list
wrong:
$ python -c "from importlib_metadata import version; print(version(\"numpy\"))"
1.17.3
$ python -c "import numpy; print(numpy.__version__)"
1.17.3
$ pip freeze | grep numpy
numpy==1.18.0
$ conda list | grep numpy
numpy 1.18.0 pypi_0 pypi

imperative and declarative describe two opposing styles of programming. imperative is the traditional "step by step recipe" approach while declarative is more "this is what i want, now you work out how to do it".
these two approaches occur throughout programming - even with the same language and the same program. generally the declarative approach is considered preferable, because it frees the programmer from having to specify so many details, while also having less chance for bugs (if you describe the result you want, and some well-tested automatic process can work backwards from that to define the steps then you might hope that things are more reliable than having to specify each step by hand).
on the other hand, an imperative approach gives you more low level control - it's the "micromanager approach" to programming. and that can allow the programmer to exploit knowledge about the problem to give a more efficient answer. so it's not unusual for some parts of a program to be written in a more declarative style, but for the speed-critical parts to be more imperative.
as you might imagine, the language you use to write a program affects how declarative you can be - a language that has built-in "smarts" for working out what to do given a description of the result is going to allow a much more declarative approach than one where the programmer needs to first add that kind of intelligence with imperative code before being able to build a more declarative layer on top. so, for example, a language like prolog is considered very declarative because it has, built-in, a process that searches for answers.
so far, you'll notice that i haven't mentioned functional programming. that's because it's a term whose meaning isn't immediately related to the other two. at its most simple, functional programming means that you use functions. in particular, that you use a language that supports functions as "first class values" - that means that not only can you write functions, but you can write functions that write functions (that write functions that...), and pass functions to functions. in short - that functions are as flexible and common as things like strings and numbers.
it might seem odd, then, that functional, imperative and declarative are often mentioned together. the reason for this is a consequence of taking the idea of functional programming "to the extreme". a function, in it's purest sense, is something from maths - a kind of "black box" that takes some input and always gives the same output. and that kind of behaviour doesn't require storing changing variables. so if you design a programming language whose aim is to implement a very pure, mathematically influenced idea of functional programming, you end up rejecting, largely, the idea of values that can change (in a certain, limited, technical sense).
and if you do that - if you limit how variables can change - then almost by accident you end up forcing the programmer to write programs that are more declarative, because a large part of imperative programming is describing how variables change, and you can no longer do that! so it turns out that functional programming - particularly, programming in a functional language - tends to give more declarative code.
to summarise, then:
imperative and declarative are two opposing styles of programming (the same names are used for programming languages that encourage those styles)
functional programming is a style of programming where functions become very important and, as a consequence, changing values become less important. the limited ability to specify changes in values forces a more declarative style.
so "functional programming" is often described as "declarative".

This is an old question, but answering for gathering knowledge. We have an original form with a button to show the new form.
The code for the button click is below
private void button1_Click(object sender, EventArgs e)
{
New_Form new_Form = new New_Form();
new_Form.Show();
}
Now when click is made, New Form is shown. Since, you want to hide after 2 seconds we are adding a onload event to the new form designer
this.Load += new System.EventHandler(this.OnPageLoad);
This OnPageLoad function runs when that form is loaded
In NewForm.cs ,
public partial class New_Form : Form
{
private Timer formClosingTimer;
private void OnPageLoad(object sender, EventArgs e)
{
formClosingTimer = new Timer(); // Creating a new timer
formClosingTimer.Tick += new EventHandler(CloseForm); // Defining tick event to invoke after a time period
formClosingTimer.Interval = 2000; // Time Interval in miliseconds
formClosingTimer.Start(); // Starting a timer
}
private void CloseForm(object sender, EventArgs e)
{
formClosingTimer.Stop(); // Stoping timer. If we dont stop, function will be triggered in regular intervals
this.Close(); // Closing the current form
}
}
In this new form , a timer is used to invoke a method which closes that form.
Here is the new form which automatically closes after 2 seconds, we will be able operate on both the forms where no interference between those two forms.
For your knowledge,
form.close()
will free the memory and we can never interact with that form again
form.hide()
will just hide the form, where the code part can still run

This can be achieved in various methods in Swift 3.0 Worked on Latest version MAY- 2019
Directly assign the Height & Width values for a view:
userView.frame.size.height = 0
userView.frame.size.width = 10
Assign the CGRect for the Frame
userView.frame = CGRect(x:0, y: 0, width:0, height:0)
Method Details:
CGRect(x: point of X, y: point of Y, width: Width of View, height: Height of View)
Using an Extension method for CGRECT
Add following extension code in any swift file,
extension CGRect {
init(_ x:CGFloat, _ y:CGFloat, _ w:CGFloat, _ h:CGFloat) {
self.init(x:x, y:y, width:w, height:h)
}
}
Use the following code anywhere in your application for the view to set the size parameters
userView.frame = CGRect(1, 1, 20, 45)
You can use the following method below although, it does have a flaw, because it can be faked, except if you can add another line of code to make sure the request comes only from your server either by using Javascript. You can place this code in the Body section of your HTML code, so the error shows there.
<?
if(!isset($_SERVER['HTTP_REQUEST'])) { include ('error_file.php'); }
else { ?>
Place your other HTML code here
<? } ?>
End it like this, so the output of the error will always show within the body section, if that's how you want it to be.
BABEL TEAM UPDATE:
We're super excited that you're trying to use ES2015 syntax, but instead of continuing yearly presets, the team recommends using babel-preset-env. By default, it has the same behavior as previous presets to compile ES2015+ to ES5
If you are using Babel version 7 you will need to run npm install @babel/preset-env and have "presets": ["@babel/preset-env"] in your .babelrc
configuration.
This will compile all latest features to es5 transpiled code:
Prerequisites:
Step-1:: npm install --save-dev @babel/preset-env
Step-2: In order to compile JSX
code to es5 babel provides @babel/preset-react
package to convert reactjsx
extension file to native browser understandable code.
Step-3: npm install --save-dev @babel/preset-react
Step-4: create .babelrc
file inside root path path of your project where webpack.config.js
exists.
{
"presets": ["@babel/preset-env", "@babel/preset-react"]
}
Step-5: webpack.config.js
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
mode: 'development',
entry: path.resolve(__dirname, 'src/index.js'),
output: {
path: path.resolve(__dirname, 'output'),
filename: 'bundle.js'
},
resolve: {
extensions: ['.js', '.jsx']
},
module: {
rules: [{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader'
}
},

}
]
},

The reason this puts NaN
into a column is because df.index
and the Index
of your right-hand-side object are different. @zach shows the proper way to assign a new column of zeros. In general, pandas
tries to do as much alignment of indices as possible. One downside is that when indices are not aligned you get NaN
wherever they aren't aligned. Play around with the reindex
and align
methods to gain some intuition for alignment works with objects that have partially, totally, and not-aligned-all aligned indices. For example here's how DataFrame.align()
works with partially aligned indices:
In [7]: from pandas import DataFrame
In [8]: from numpy.random import randint
In [9]: df = DataFrame({'a': randint(3, size=10)})

I see a lot of examples of the Microsoft Dispose pattern which is really an anti-pattern. As many have pointed out the code in the question does not require IDisposable at all. But if you where going to implement it please don't use the Microsoft pattern. Better answer would be following the suggestions in this article:

The only other thing that would likely be helpful is suppressing that code analysis warning... https://docs.microsoft.com/en-us/visualstudio/code-quality/in-source-suppression-overview?view=vs-2017
From the jQuery documentation - http://api.jquery.com/jQuery.ajax/
contentType When sending data to the server, use this content type.
dataType The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response
"text": A plain text string.
So you want contentType to be application/json
and dataType to be text
:
$.ajax({
type : "POST",
url : /v1/user,
dataType : "text",
contentType: "application/json",
data : dataAttribute,
success : function() {
},
error : function(error) {
}
});
You can't do it in a single query, but you could do it within a transaction. Do the initial MAX() select and lock the table, then do the insert. The transaction ensures that nothing will interrupt the two queries, and the lock ensures that nothing else can try doing the same thing elsewhere at the same time.

This works:
word = str(input("Enter string:"))
notChar = 0
isChar = 0
for char in word:
if not char.isalpha():
notChar += 1
else:
isChar += 1
print(isChar, " were letters; ", notChar, " were not letters.")
The answer to the question how to convert a .cer file into a .crt file (they are encoded differently!) is:
openssl pkcs7 -print_certs -in certificate.cer -out certificate.crt
A ClusterIP exposes the following:
spec.clusterIp:spec.ports[*].port
You can only access this service while inside the cluster. It is accessible from its spec.clusterIp
port. If a spec.ports[*].targetPort
is set it will route from the port to the targetPort. The CLUSTER-IP you get when calling kubectl get services
is the IP assigned to this service within the cluster internally.
A NodePort exposes the following:
<NodeIP>:spec.ports[*].nodePort
spec.clusterIp:spec.ports[*].port
If you access this service on a nodePort from the node's external IP, it will route the request to spec.clusterIp:spec.ports[*].port
, which will in turn route it to your spec.ports[*].targetPort
, if set. This service can also be accessed in the same way as ClusterIP.
Your NodeIPs are the external IP addresses of the nodes. You cannot access your service from spec.clusterIp:spec.ports[*].nodePort
.
A LoadBalancer exposes the following:
spec.loadBalancerIp:spec.ports[*].port
<NodeIP>:spec.ports[*].nodePort
spec.clusterIp:spec.ports[*].port
You can access this service from your load balancer's IP address, which routes your request to a nodePort, which in turn routes the request to the clusterIP port. You can access this service as you would a NodePort or a ClusterIP service as well.

A simple solution is encapsulate code of button event in a function, and call it when you add TRs too:
var i = 1;
$("#addbutton").click(function() {
$("table tr:first").clone().find("input").each(function() {
$(this).val('').attr({
'id': function(_, id) {return id + i },
'name': function(_, name) { return name + i },
'value': ''
});
}).end().appendTo("table");
i++;
applyRemoveEvent();
});
function applyRemoveEvent(){
$('button.removebutton').on('click',function() {
alert("aa");
$(this).closest( 'tr').remove();
return false;
});
};
applyRemoveEvent();
$ echo "C:\Windows\Folder\File.txt" | sed -e 's/\\/\//g'
C:/Windows/Folder/File.txt
The sed command in this case is 's/OLD_TEXT/NEW_TEXT/g'
.
The leading 's' just tells it to search for OLD_TEXT and replace it with NEW_TEXT.
The trailing 'g' just says to replace all occurrences on a given line, not just the first.
And of course you need to separate the 's', the 'g', the old, and the new from each other. This is where you must use forward slashes as separators.
For your case OLD_TEXT == '\'
and NEW_TEXT == '/'
. But you can't just go around typing slashes and expecting things to work as expected be taken literally while using them as separators at the same time. In general slashes are quite special and must be handled as such. They must be 'escaped' (i.e. preceded) by a backslash.
So for you, OLD_TEXT == '\\'
and NEW_TEXT == '\/'
. Putting these inside the 's/OLD_TEXT/NEW_TEXT/g'
paradigm you get
's/\\/\//g'
. That reads as
's
/ \\
/ \/
/ g
' and after escapes is
's
/ \
/ /
/ g
' which will replace all backslashes with forward slashes.
You can use the DATE_ADD()
function:
... WHERE DATE(DATE_ADD(eventdate, INTERVAL -1 DAY)) = CURRENT_DATE
It can also be used in the SELECT
statement:
SELECT DATE_ADD('2010-05-11', INTERVAL 1 DAY) AS Tomorrow;
+------------+
| Tomorrow |
+------------+
| 2010-05-12 |
+------------+
1 row in set (0.00 sec)
Alternatively you can grant the user DROP_ANY_TABLE
privilege if need be and the procedure will run as is without the need for any alteration. Dangerous maybe but depends what you're doing :)
This is for 32 bit, we need to change the size if we consider 8 bits.
void bitReverse(int num)
{
int num_reverse = 0;
int size = (sizeof(int)*8) -1;
int i=0,j=0;
for(i=0,j=size;i<=size,j>=0;i++,j--)
{
if((num >> i)&1)
{
num_reverse = (num_reverse | (1<<j));
}
}
printf("\n rev num = %d\n",num_reverse);
}
Reading the input integer "num" in LSB->MSB order and storing in num_reverse in MSB->LSB order.
For the C-runtime go to the project settings, choose C/C++ then 'Code Generation'. Change the 'runtime library' setting to 'multithreaded' instead of 'multithreaded dll'.
If you are using any other libraries you may need to tell the linker to ignore the dynamically linked CRT explicitly.
You might need to set permissions at the database level that allows your schema owner to restore the dump.
You may also try try -Dmaven.clean.failOnError=false
(from Maven FAQ)
Assuming that you have access to Prototype, this could work. I wrote this code for myself just a few minutes ago; I only needed a single key at a time, so this isn't time efficient for big lists of key:value pairs or for spitting out multiple key names.
function key(int) {
var j = -1;
for(var i in this) {
j++;
if(j==int) {
return i;
} else {
continue;
}
}
}
Object.prototype.key = key;
This is numbered to work the same way that arrays do, to save headaches. In the case of your code:
buttons.key(0) // Should result in "button1"
Deprecated in general means "don't use it".
A deprecated function may or may not work, but it is not guaranteed to work.
First off, a PetStore
is not a farm.
Let's get past this though. You actually don't need access to the private members, you have everything you need in the public interface:
Animal_* getAnimal_(int i);
void addAnimal_(Animal_* newAnimal);
These are the methods you're given access to and these are the ones you should use.
I mean I did this Inheritance so I can add animals to my PetStore but now since sizeF is private how can I do that ??
Simple, you call addAnimal
. It's public
and it also increments sizeF
.
Also, note that
PetStore()
{
idF=0;
};
is equivalent to
PetStore() : Farm()
{
idF=0;
};
i.e. the base constructor is called, base members are initialized.
Simply put, linear regression is a regression algorithm, which outpus a possible continous and infinite value; logistic regression is considered as a binary classifier algorithm, which outputs the 'probability' of the input belonging to a label (0 or 1).
To solve this, I opened httpd.conf
and changed the following line:
Allow from 127.0.0.1
to:
Allow from 127.0.0.1 ::1
If you're using python3, you can try this too:
python3 -m pip install --upgrade Scrapy --trusted-host pypi.org --trusted-host files.pythonhosted.org
Your installation is missing some php modules, there should be a list of required modules in the phpmyadmin readme. If you recently enabled the modules, try restarting the apache service / daemon.
Edit: As it seems, there is no single "enable these modules" in the docs, so enable either mysql
or mysqli
in your php.ini (you might need to install it first).
The two messages are not important if you do not intend to upload or download compressed file within phpMyAdmin. If you do, enable the zlib
and / or bz2
modules.
You can use the FileWriter(String fileName, boolean append)
constructor if you want to append data to file.
Change your code to this:
output = new BufferedWriter(new FileWriter(my_file_name, true));
From FileWriter javadoc:
Constructs a FileWriter object given a file name. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
Explicit access to module level variables by accessing them explicity on the module
In short: The technique described here is the same as in steveha's answer, except, that no artificial helper object is created to explicitly scope variables. Instead the module object itself is given a variable pointer, and therefore provides explicit scoping upon access from everywhere. (like assignments in local function scope).
Think of it like self for the current module instead of the current instance !
# db.py
import sys
# this is a pointer to the module object instance itself.
this = sys.modules[__name__]
# we can explicitly make assignments on it
this.db_name = None
def initialize_db(name):
if (this.db_name is None):
# also in local function scope. no scope specifier like global is needed
this.db_name = name
# also the name remains free for local use
db_name = "Locally scoped db_name variable. Doesn't do anything here."
else:
msg = "Database is already initialized to {0}."
raise RuntimeError(msg.format(this.db_name))
As modules are cached and therefore import only once, you can import db.py
as often on as many clients as you want, manipulating the same, universal state:
# client_a.py
import db
db.initialize_db('mongo')
# client_b.py
import db
if (db.db_name == 'mongo'):
db.db_name = None # this is the preferred way of usage, as it updates the value for all clients, because they access the same reference from the same module object
# client_c.py
from db import db_name
# be careful when importing like this, as a new reference "db_name" will
# be created in the module namespace of client_c, which points to the value
# that "db.db_name" has at import time of "client_c".
if (db_name == 'mongo'): # checking is fine if "db.db_name" doesn't change
db_name = None # be careful, because this only assigns the reference client_c.db_name to a new value, but leaves db.db_name pointing to its current value.
As an additional bonus I find it quite pythonic overall as it nicely fits Pythons policy of Explicit is better than implicit.
Adding one more to the list, because I find all of the above not quite "KISS" enough.
This one uses regex to find either commas or newlines while skipping over quoted items. Hopefully this is something noobies can read through on their own. The splitFinder
regexp has three things it does (split by a |
):
,
- finds commas\r?\n
- finds new lines, (potentially with carriage return if the exporter was nice)"(\\"|[^"])*?"
- skips anynthing surrounded in quotes, because commas and newlines don't matter in there. If there is an escaped quote \\"
in the quoted item, it will get captured before an end quote can be found.const splitFinder = /,|\r?\n|"(\\"|[^"])*?"/g;_x000D_

It's simpler than I initially thought.. Basically you have a page that does nothing, until the data you want to send is available (say, a new message arrives).
Here is a really basic example, which sends a simple string after 2-10 seconds. 1 in 3 chance of returning an error 404 (to show error handling in the coming Javascript example)
msgsrv.php
<?php
if(rand(1,3) == 1){
/* Fake an error */
header("HTTP/1.0 404 Not Found");
die();
}
/* Send a string after a random number of seconds (2-10) */
sleep(rand(2,10));
echo("Hi! Have a random number: " . rand(1,10));
?>
Note: With a real site, running this on a regular web-server like Apache will quickly tie up all the "worker threads" and leave it unable to respond to other requests.. There are ways around this, but it is recommended to write a "long-poll server" in something like Python's twisted, which does not rely on one thread per request. cometD is an popular one (which is available in several languages), and Tornado is a new framework made specifically for such tasks (it was built for FriendFeed's long-polling code)... but as a simple example, Apache is more than adequate! This script could easily be written in any language (I chose Apache/PHP as they are very common, and I happened to be running them locally)
Then, in Javascript, you request the above file (msg_srv.php
), and wait for a response. When you get one, you act upon the data. Then you request the file and wait again, act upon the data (and repeat)
What follows is an example of such a page.. When the page is loaded, it sends the initial request for the msgsrv.php
file.. If it succeeds, we append the message to the #messages
div, then after 1 second we call the waitForMsg function again, which triggers the wait.
The 1 second setTimeout()
is a really basic rate-limiter, it works fine without this, but if msgsrv.php
always returns instantly (with a syntax error, for example) - you flood the browser and it can quickly freeze up. This would better be done checking if the file contains a valid JSON response, and/or keeping a running total of requests-per-minute/second, and pausing appropriately.
If the page errors, it appends the error to the #messages
div, waits 15 seconds and then tries again (identical to how we wait 1 second after each message)
The nice thing about this approach is it is very resilient. If the clients internet connection dies, it will timeout, then try and reconnect - this is inherent in how long polling works, no complicated error-handling is required

PDF2SVG version 6.0 from PDFTron does a reasonable job. It produces OpenType (.otf
) fonts by default. Use --preserve_fontnames
to preserve "the font/font-family naming scheme as obtained from the source file."
PDF2SVG is a commercial product, but you can download a free demo executable (which includes watermarks on the SVG output but doesn't otherwise restrict usage). There may be other PDFTron products that also extract fonts, but I only recently discovered PDF2SVG myself.
Simply floating both elements left achieves the same result.

To reverse a test, use "!". That is equivalent to the "not" logical operator in other languages. Try this:
if [ ! -f /tmp/foo.txt ];
then
echo "File not found!"
fi
Or written in a slightly different way:
if [ ! -f /tmp/foo.txt ]
then echo "File not found!"
fi
Or you could use:
if ! [ -f /tmp/foo.txt ]
then echo "File not found!"
fi
Or, presing all together:
if ! [ -f /tmp/foo.txt ]; then echo "File not found!"; fi
Which may be written (using then "and" operator: &&) as:
[ ! -f /tmp/foo.txt ] && echo "File not found!"
Which looks shorter like this:
[ -f /tmp/foo.txt ] || echo "File not found!"
Suppose your "Don't Check" list is on Sheet2 in cells A1:A100
, say, and your current client IDs are in Sheet1 in Column A.
What you would do is:
Conditional Formatting
> New Rule
> Use a Formula to determine which cells to format
=ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0))
and select how you want those rows formattedAnd that should do the trick.
Assuming you are generating a shared library, most probably what happens is that the variant of liblog4cplus.a
you are using wasn't compiled with -fPIC
. In linux, you can confirm this by extracting the object files from the static library and checking their relocations:
ar -x liblog4cplus.a
readelf --relocs fileappender.o | egrep '(GOT|PLT|JU?MP_SLOT)'
If the output is empty, then the static library is not position-independent and cannot be used to generate a shared object.
Since the static library contains object code which was already compiled, providing the -fPIC flag won't help.
You need to get ahold of a version of liblog4cplus.a
compiled with -fPIC
and use that one instead.
C# equivalent of your code is
class Imagedata : PDFStreamEngine
{
// C# uses "base" keyword whenever Java uses "super"
// so instead of super(...) in Java we should call its C# equivalent (base):
public Imagedata()
: base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true))
{ }
// Java methods are virtual by default, when C# methods aren't.
// So we should be sure that processOperator method in base class
// (that is PDFStreamEngine)
// declared as "virtual"
protected override void processOperator(PDFOperator operations, List arguments)
{
base.processOperator(operations, arguments);
}
}
you can use String format to include variables within strings
i use this code to include 2 variable in string:
String myString = String.format("this is my string %s %2d", variable1Name, variable2Name);

To remove all files from staging area use -
git reset
To remove specific file use -
git reset "File path"
The removeClass function takes a function argument since jQuery 1.4.
$("#hello").removeClass (function (index, className) {
return (className.match (/(^|\s)color-\S+/g) || []).join(' ');
});

Also made a little script using RDFa (you can also use microdata or other formats) Check it out on google This script also keeps in mind your site structure.

//Use RDFa breadcrumb, can also be used for microformats etc.
$bc = '<div xmlns:v="http://rdf.data-vocabulary.org/#" id="crums">'.$text;
//Get the website:
$site = 'http://'.$_SERVER['HTTP_HOST'];
//Get all vars en skip the empty ones
$crumbs = array_filter( explode("/",$_SERVER["REQUEST_URI"]) );
//Create the home breadcrumb
$bc .= '<span typeof="v:Breadcrumb"><a href="'.$site.'" rel="v:url" property="v:title">'.$home.'</a>'.$sep.'</span>';
//Count all not empty breadcrumbs
$nm = count($crumbs);
$i = 1;
//Loop the crumbs
foreach($crumbs as $crumb){
//Make the link look nice
$link = ucfirst( str_replace( array(".php","-","_"), array(""," "," ") ,$crumb) );
//Loose the last seperator
$sep = $i==$nm?'':$sep;
//Add crumbs to the root
$site .= '/'.$crumb;
//Make the next crumb
$bc .= '<span typeof="v:Breadcrumb"><a href="'.$site.'" rel="v:url" property="v:title">'.$link.'</a>'.$sep.'</span>';
$i++;
}
$bc .= '</div>';
//Return the result
return $bc;}
A great way using C# and Linq here:
public static bool HasSpecialCharacter(this string s)
{
foreach (var c in s)
{
if(!char.IsLetterOrDigit(c))
{
return true;
}
}
return false;
}
And access it like this:
myString.HasSpecialCharacter();
If you got a html page like this:
<body onbeforecopy = "return false" ondragstart = "return false" onselectstart = "return false" oncontextmenu = "return false" onselect = "document.selection.empty()" oncopy = "document.selection.empty()">
There a simple way to disable all events:
document.write(document.body.innerHTML)
You got the html content and lost other things.
Closed formula for the longest int
(I used int
here, but works for any signed integral type):
1 + (int) ceil((8*sizeof(int)-1) * log10(2))
Explanation:
sizeof(int) // number bytes in int
8*sizeof(int) // number of binary digits (bits)
8*sizeof(int)-1 // discount one bit for the negatives
(8*sizeof(int)-1) * log10(2) // convert to decimal, because:
// 1 bit == log10(2) decimal digits
(int) ceil((8*sizeof(int)-1) * log10(2)) // round up to whole digits
1 + (int) ceil((8*sizeof(int)-1) * log10(2)) // make room for the minus sign
For an int
type of 4 bytes, the result is 11. An example of 4 bytes int
with 11 decimal digits is: "-2147483648".
If you want the number of decimal digits of some int
value, you can use the following function:
unsigned base10_size(int value)
{
if(value == 0) {
return 1u;
}
unsigned ret;
double dval;
if(value > 0) {
ret = 0;
dval = value;
} else {
// Make room for the minus sign, and proceed as if positive.
ret = 1;
dval = -double(value);
}
ret += ceil(log10(dval+1.0));
return ret;
}
I tested this function for the whole range of int
in g++ 9.3.0 for x86-64.
I would probably do something along the lines of
<div id='search-logo-bar'><input type='text'/></div>
with css
div#search-logo-bar {
padding-left:10%;
background:#333 url(logo.png) no-repeat left center;
background-size:10%;
}
input[type='text'] {
display:block;
width:100%;
}

$a = 'This', 'Is', 'a', 'cat'
Using double quotes (and optionally use the separator $ofs
)
# This Is a cat
"$a"
# This-Is-a-cat
$ofs = '-' # after this all casts work this way until $ofs changes!
"$a"
Using operator join
# This-Is-a-cat
$a -join '-'
# ThisIsacat
-join $a
Using conversion to [string]
# This Is a cat
[string]$a
# This-Is-a-cat
$ofs = '-'
[string]$a
I would try to solve this without VBA. Just select this space and use replace (change to nothing) on that worksheet you're trying to get rid off those spaces.
If you really want to use VBA I believe you could select first character
strSpace = left(range("A1").Value,1)
and use replace function in VBA the same way
Range("A1").Value = Replace(Range("A1").Value, strSpace, "")
or
for each cell in selection.cells
cell.value = replace(cell.value, strSpace, "")

I have seen instances where the remote became out of sync and needed to be updated. If a reset --hard
or a branch -D
fail to work, try
git pull origin
git reset --hard
The simplest explanation would be by implementing Runnable
we can assign the same object to multiple threads and each Thread
shares the same object states and behavior.
For example, suppose there are two threads, thread1 puts an integer in an array and thread2 takes integers from the array when the array is filled up. Notice that in order for thread2 to work it needs to know the state of array, whether thread1 has filled it up or not.
Implementing Runnable
lets you to have this flexibility to share the object whereas extends Thread
makes you to create new objects for each threads therefore any update that is done by thread1 is lost to thread2.
Depending on why you are doing this, using a std::set might be a better idea than std::vector.
It allows each element to occur only once. If you add it multiple times, there will only be one instance to erase anyway. This will make the erase operation trivial. The erase operation will also have lower time complexity than on the vector, however, adding elements is slower on the set so it might not be much of an advantage.
This of course won't work if you are interested in how many times an element has been added to your vector or the order the elements were added.
Set step="any"
. Works fine.

JEP 354: Switch Expressions (Preview) in JDK-13 and JEP 361: Switch Expressions (Standard) in JDK-14 will extend the switch statement so it can be used as an expression.
Now you can:
case L ->
):
The code to the right of a "case L ->" switch label is restricted to be an expression, a block, or (for convenience) a throw statement.
To yield a value from a switch expression, the
break
with value statement is dropped in favor of ayield
statement.
So the demo from the answers (1, 2) might look like this:
public static void main(String[] args) {
switch (args[0]) {
case "Monday", "Tuesday", "Wednesday" -> System.out.println("boring");
case "Thursday" -> System.out.println("getting better");
case "Friday", "Saturday", "Sunday" -> System.out.println("much better");
}
If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:
Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);
Hope it helps.
From Crockford
By convention, we make a private that variable. This is used to make the object available to the private methods. This is a workaround for an error in the ECMAScript Language Specification which causes this to be set incorrectly for inner functions.
function usesThis(name) {
this.myName = name;
function returnMe() {
return this; //scope is lost because of the inner function
}
return {
returnMe : returnMe
}
}
function usesThat(name) {
var that = this;
this.myName = name;
function returnMe() {
return that; //scope is baked in with 'that' to the "class"
}
return {
returnMe : returnMe
}
}
var usesthat = new usesThat('Dave');
var usesthis = new usesThis('John');
alert("UsesThat thinks it's called " + usesthat.returnMe().myName + '\r\n' +
"UsesThis thinks it's called " + usesthis.returnMe().myName);
This alerts...
UsesThat thinks it's called Dave
UsesThis thinks it's called undefined
What’s the difference between compiled and interpreted language?
The difference is not in the language; it is in the implementation.
Having got that out of my system, here's an answer:
In a compiled implementation, the original program is translated into native machine instructions, which are executed directly by the hardware.
In an interpreted implementation, the original program is translated into something else. Another program, called "the interpreter", then examines "something else" and performs whatever actions are called for. Depending on the language and its implementation, there are a variety of forms of "something else". From more popular to less popular, "something else" might be
Binary instructions for a virtual machine, often called bytecode, as is done in Lua, Python, Ruby, Smalltalk, and many other systems (the approach was popularized in the 1970s by the UCSD P-system and UCSD Pascal)
A tree-like representation of the original program, such as an abstract-syntax tree, as is done for many prototype or educational interpreters
A tokenized representation of the source program, similar to Tcl
The characters of the source program, as was done in MINT and TRAC
One thing that complicates the issue is that it is possible to translate (compile) bytecode into native machine instructions. Thus, a successful intepreted implementation might eventually acquire a compiler. If the compiler runs dynamically, behind the scenes, it is often called a just-in-time compiler or JIT compiler. JITs have been developed for Java, JavaScript, Lua, and I daresay many other languages. At that point you can have a hybrid implementation in which some code is interpreted and some code is compiled.

Following on from the answer by @marcel I found some functions were still missing on the cloned object. e.g.
function MyObject() {
var methodAValue = null,
methodBValue = null
Object.defineProperty(this, "methodA", {
get: function() { return methodAValue; },
set: function(value) {
methodAValue = value || {};
},
enumerable: true
});
Object.defineProperty(this, "methodB", {
get: function() { return methodAValue; },
set: function(value) {
methodAValue = value || {};
}
});
}
where on MyObject I could clone methodA but methodB was excluded. This occurred because it is missing
enumerable: true
which meant it did not show up in
for(let key in item)
Instead I switched over to
Object.getOwnPropertyNames(item).forEach((key) => {
....
});
which will include non-enumerable keys.
I also found that the prototype (proto) was not cloned. For that I ended up using
if (obj.__proto__) {
copy.__proto__ = Object.assign(Object.create(Object.getPrototypeOf(obj)), obj);
}
PS: Frustrating that I could not find a built in function to do this.
No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:variable name="mapping">
<item key="1" v1="A" v2="B" />
<item key="2" v1="X" v2="Y" />
</xsl:variable>
<xsl:variable name="mappingNode"
select="document('')//xsl:variable[@name = 'mapping']" />
<xsl:template match="....">
<xsl:variable name="testVariable" select="'1'" />
<xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />
<xsl:variable name="variable1" select="$values/@v1" />
<xsl:variable name="variable2" select="$values/@v2" />
</xsl:template>
</xsl:stylesheet>
In fact, once you've got the values
variable, you may not even need separate variable1
and variable2
variables. You could just use $values/@v1
and $values/@v2
instead.
Here is a good article on creating and adding a class library. Even shows how to create Methods through the method wizard and how to use it in the application
This works for all databases and works by renaming each table with maatkit mysql toolkit
Use mk-find to print and rename each table. The man page has many more options and examples
mk-find --dblike OLD_DATABASE --print --exec "RENAME TABLE %D.%N TO NEW_DATABASE.%N"
If you have maatkit installed (which is very easy), then this is the simplest way to do it.
I had faced the same issue because of some dll files were missing from References of VS13. I went to the location http://scn.sap.com/docs/DOC-7824 and installed the newest pack. It resolved the issue.
Taking advantage of str.split's behavior with no sep parameter:
>>> s = " \t foo \n bar "
>>> "".join(s.split())
'foobar'
If you just want to remove spaces instead of all whitespace:
>>> s.replace(" ", "")
'\tfoo\nbar'
Even though efficiency isn't the primary goal—writing clear code is—here are some initial timings:
$ python -m timeit '"".join(" \t foo \n bar ".split())'
1000000 loops, best of 3: 1.38 usec per loop
$ python -m timeit -s 'import re' 're.sub(r"\s+", "", " \t foo \n bar ")'
100000 loops, best of 3: 15.6 usec per loop
Note the regex is cached, so it's not as slow as you'd imagine. Compiling it beforehand helps some, but would only matter in practice if you call this many times:
$ python -m timeit -s 'import re; e = re.compile(r"\s+")' 'e.sub("", " \t foo \n bar ")'
100000 loops, best of 3: 7.76 usec per loop
Even though re.sub is 11.3x slower, remember your bottlenecks are assuredly elsewhere. Most programs would not notice the difference between any of these 3 choices.
Solve that by using std::basic_string<TCHAR>
instead of std::string
and it should work fine regardless of your character setting.
The solution with copying 32-bit libs over to 64-bit did not work for me. What worked was unchecking Target Platform Prefer 32-bit check mark in project properties.
Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -
sign before value
:
ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) +
geom_bar(stat = "identity")
which gives:
Used data:
corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
value = c(7L, 75L, 70L, 5L, 10L, 47L)),
class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))
You can't create a 'const' array because arrays are objects and can only be created at runtime and const entities are resolved at compile time.
What you can do instead is to declare your array as "readonly". This has the same effect as const except the value can be set at runtime. It can only be set once and it is thereafter a readonly (i.e. const) value.
Just use:
$("input:empty").length == 0;
If it's zero, none are empty.
To be a bit smarter though and also filter out items with just spaces in, you could do:
$("input").filter(function () {
return $.trim($(this).val()).length == 0
}).length == 0;
How about:
update table
set columnname = columnname + 1
where id = <some id>
You can use "find" for remove all files in the /objects
directory with 0 in size with the command:
find .git/objects/ -size 0 -delete
Backup is recommended.
For getting AppId (or package name, how some says), just call this:
But be sure that you importing BuildConfig
with your app id packages path
BuildConfig.APPLICATION_ID
The crux of the solution is setting
CURLOPT_RETURNTRANSFER => true
then
$response = curl_exec($ch);
CURLOPT_RETURNTRANSFER tells PHP to store the response in a variable instead of printing it to the page, so $response will contain your response. Here's your most basic working code (I think, didn't test it):
// init curl object
$ch = curl_init();
// define options
$optArray = array(
CURLOPT_URL => 'http://www.google.com',
CURLOPT_RETURNTRANSFER => true
);
// apply those options
curl_setopt_array($ch, $optArray);
// execute request and get response
$result = curl_exec($ch);
If "ReferenceError: Model is not defined" error is raised, then you might try to use the following method:
$(document).ready(function () {
@{ var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
var json = serializer.Serialize(Model);
}
var model = @Html.Raw(json);
if(model != null && @Html.Raw(json) != "undefined")
{
var id= model.Id;
var mainFloorPlanId = model.MainFloorPlanId ;
var imageDirectory = model.ImageDirectory ;
var iconsDirectory = model.IconsDirectory ;
}
});
Hope this helps...
Very C/C++ style solution:
foo = 5
objectsList = [3, 6, 5, 9, 10]
prev = nex = 0
currentIndex = 0
indexHigher = len(objectsList)-1 #control the higher limit of list
found = False
prevFound = False
nexFound = False
#main logic:
for currentValue in objectsList: #getting each value of list
if currentValue == foo:
found = True
if currentIndex > 0: #check if target value is in the first position
prevFound = True
prev = objectsList[currentIndex-1]
if currentIndex < indexHigher: #check if target value is in the last position
nexFound = True
nex = objectsList[currentIndex+1]
break #I am considering that target value only exist 1 time in the list
currentIndex+=1
if found:
print("Value %s found" % foo)
if prevFound:
print("Previous Value: ", prev)
else:
print("Previous Value: Target value is in the first position of list.")
if nexFound:
print("Next Value: ", nex)
else:
print("Next Value: Target value is in the last position of list.")
else:
print("Target value does not exist in the list.")

one way is to write an abstract test case that corresponds to your abstract class, then write concrete test cases that subclass your abstract test case. do this for each concrete subclass of your original abstract class (i.e. your test case hierarchy mirrors your class hierarchy). see Test an interface in the junit recipies book: http://safari.informit.com/9781932394238/ch02lev1sec6. https://www.manning.com/books/junit-recipes or https://www.amazon.com/JUnit-Recipes-Practical-Methods-Programmer/dp/1932394230 if you don't have a safari account.

I think what you are being asked to do (or perhaps asking yourself?) is take a character value which matches the name of a column in a particular dataframe (possibly also given as a character). There are two tricks here. Most people learn to extract columns with the "$" operator and that won't work inside a function if the function is passed a character vecor. If the function is also supposed to accept character argument then you will need to use the get
function as well:
df1 <- data.frame(a=1:10, b=11:20)
mean_col <- function( dfrm, col ) mean( get(dfrm)[[ col ]] )
mean_col("df1", "b")
# [1] 15.5
There is sort of a semantic boundary between ordinary objects like character vectors and language objects like the names of objects. The get
function is one of the functions that lets you "promote" character values to language level evaluation. And the "$" function will NOT evaluate its argument in a function, so you need to use"[[". "$" only is useful at the console level and needs to be completely avoided in functions.

Things that DID NOT WORK for me with an iPad 4/iOS 6:
My request containing: Cache-Control:no-cache
//asp.net's:
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache)
Adding cache: false to my jQuery ajax call
$.ajax(
{
url: postUrl,
type: "POST",
cache: false,
...
Only this did the trick:
var currentTime = new Date();
var n = currentTime.getTime();
postUrl = "http://www.example.com/test.php?nocache="+n;
$.post(postUrl, callbackFunction);
We can simply do like this.
formData = new FormData;
words = ["apple", "ball", "cat"]
words.forEach((item) => formData.append("words[]", item))
// verify the data
console.log(formData.getAll("words[]"))
//["apple", "ball", "cat"]
_x000D_
On server-side you will get words = ["apple", "ball", "cat"]
In my Reactive form, I needed to mark a field as invalid if another field was checked. In ng version 7 I did the following:
const checkboxField = this.form.get('<name of field>');
const dropDownField = this.form.get('<name of field>');
this.checkboxField$ = checkboxField.valueChanges
.subscribe((checked: boolean) => {
if(checked) {
dropDownField.setValidators(Validators.required);
dropDownField.setErrors({ required: true });
dropDownField.markAsDirty();
} else {
dropDownField.clearValidators();
dropDownField.markAsPristine();
}
});
So above, when I check the box it sets the dropdown as required and marks it as dirty. If you don't mark as such it then it won't be invalid (in error) until you try to submit the form or interact with it.
If the checkbox is set to false (unchecked) then we clear the required validator on the dropdown and reset it to a pristine state.
Also - remember to unsubscribe from monitoring field changes!
You have some syntax issues with your script. Here is a fixed version:
#!/bin/bash
if [ "$seconds" -eq 0 ]; then
timezone_string="Z"
elif [ "$seconds" -gt 0 ]; then
timezone_string=$(printf "%02d:%02d" $((seconds/3600)) $(((seconds / 60) % 60)))
else
echo "Unknown parameter"

If you like, you could declare an infix
operator
to do it.
// Put this at file level anywhere in your project
infix operator ^^ { associativity left precedence 160 }
func ^^ (radix: Int, power: Int) -> Int {
return Int(pow(Double(radix), Double(power)))
}
// ...
// Then you can do this...
let i = 2 ^^ 3
// ... or
println("2³ = \(2 ^^ 3)") // Prints 2³ = 8
I used two carets so you can still use the XOR operator.
Update for Swift 3
In Swift 3 the "magic number" precedence
is replaced by precedencegroups
:
precedencegroup PowerPrecedence { higherThan: MultiplicationPrecedence }
infix operator ^^ : PowerPrecedence
func ^^ (radix: Int, power: Int) -> Int {
return Int(pow(Double(radix), Double(power)))
}
// ...
// Then you can do this...
let i2 = 2 ^^ 3
// ... or
print("2³ = \(2 ^^ 3)") // Prints 2³ = 8
Not really, in the standard. Some implementations have a nonstandard itoa() function, and you could look up Boost's lexical_cast, but if you stick to the standard it's pretty much a choice between stringstream and sprintf() (snprintf() if you've got it).
You can use this code...
public class Main {
public static void main(String args[]) {
String[] names = {"First", "Second", "Third"};//You Can Add More Names
double[] amount = {20.0, 30.0, 40.0};//You Can Add More Amount
List<Customer> customers = new ArrayList<Customer>();
int i = 0;
while (i < names.length) {
customers.add(new Customer(names[i], amount[i]));
i++;
}
}
}
It can be done in seven ways:
import com.google.common.primitives.Ints;
import org.apache.commons.lang.math.NumberUtils;
String number = "999";
Ints.tryParse
:
int result = Ints.tryParse(number);
NumberUtils.createInteger
:
Integer result = NumberUtils.createInteger(number);
NumberUtils.toInt
:
int result = NumberUtils.toInt(number);
Integer.valueOf
:
Integer result = Integer.valueOf(number);
Integer.parseInt
:
int result = Integer.parseInt(number);
Integer.decode
:
int result = Integer.decode(number);
Integer.parseUnsignedInt
:
int result = Integer.parseUnsignedInt(number);
Your example creates multiple key: value pairs if using fromkeys
. If you don't want this, you can use one key and create an alias for the key. For example if you are using a register map, your key can be the register address and the alias can be register name. That way you can perform read/write operations on the correct register.
>>> mydict = {}
>>> mydict[(1,2)] = [30, 20]
>>> alias1 = (1,2)
>>> print mydict[alias1]
[30, 20]
>>> mydict[(1,3)] = [30, 30]
>>> print mydict
{(1, 2): [30, 20], (1, 3): [30, 30]}
>>> alias1 in mydict
True
Probably because you're using unsafe code.
Are you doing something with pointers or unmanaged assemblies somewhere?
Just create .htaccess file at root and add these lines to it
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(.*)$ public/$1 [L]
</IfModule>
That's it!
The above code works on the root public_html folder. Having said that your core laravel file should be inside the public_html folder, if your directory looks like public_html/laravelapp/public and if you put the above code inside laravelapp it won't work. Therefore you must copy all your core files into public_html and put the .htaccess file there .
If you want to keep the code in a subdirectory then you can create a subdomain then this code will work for that also.
A solution using the read builtin:
IFS=':' read -a fields <<< "1:2:3:4:5"
echo "${fields[4]}"
Or, to make it more generic:
echo "${fields[-1]}" # prints the last item
Assume a dataframe with 19 rows
index=range(0,19)
index
columns=['A']
test = pd.DataFrame(index=index, columns=columns)
Keeping Column A as a constant
test['A']=10
Keeping column b as a variable given by a loop
for x in range(0,19):
test.loc[[x], 'b'] = pd.Series([x], index = [x])
You can replace the first x in pd.Series([x], index = [x])
with any value
Figured this out. Pretty simple:
new PDO("sqlsrv:server=[sqlservername];Database=[sqlserverdbname]", "[username]", "[password]");
Simply include the Apache Commons Lang JAR and use the org.apache.commons.lang.StringUtils class. You'll notice lots of methods for replacing Strings safely and efficiently.
You can view the StringUtils API at the previously linked website.

To improve the main response:
You can use the media attribute of the <link>
tag (it support media queries) in order to download just the code the user needs.
<link href="style.css" rel="stylesheet">
<link href="deviceSizeDepending.css" rel="stylesheet" media="(min-width: 40em)">
With this, the browser will download all CSS resources, regardless of the media attribute. The difference is that if the media-query of the media attribute is evaluated to false then that .css file and his content will not be render-blocking.
Therefore, it is recommended to use the media attribute in the <link>
tag since it guarantees a better user experience.
Here you can read a Google article about this issue https://developers.google.com/web/fundamentals/performance/critical-rendering-path/render-blocking-css
Some tools that will help you to automate the separation of your css code in different files according to your media-querys
Webpack https://www.npmjs.com/package/media-query-plugin https://www.npmjs.com/package/media-query-splitting-plugin
PostCSS https://www.npmjs.com/package/postcss-extract-media-query
In Netbeans, we can use Tools->Options-> General Tab - > Under proxy settings, select Use system proxy settings.
This way, it uses the proxy settings provided in Settings -> Control Panel -> Internet Options -> Connections -> Lan Settings -> use automatic configuration scripts.
If you are using maven, make sure the proxy settings are not provided there, so that it uses Netbeans settings provided above for proxy.
Hope this helps.

Try this, it's working for me.
Sender:
byte[] message = ...
Socket socket = ...
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());
dOut.writeInt(message.length); // write length of the message
dOut.write(message); // write the message
Receiver:
Socket socket = ...
DataInputStream dIn = new DataInputStream(socket.getInputStream());
int length = dIn.readInt(); // read length of incoming message
if(length>0) {
byte[] message = new byte[length];
dIn.readFully(message, 0, message.length); // read the message
}
You can only access static members using the name of the type.
Therefore, you need to either write,
MyClass.MyItem.Property1
Or (this is probably what you need to do) make Property1
an instance property by removing the static
keyword from its definition.
Static properties are shared between all instances of their class, so that they only have one value. The way it's defined now, there is no point in making any instances of your MyItem class.
In powershell :
$this_script_path = $(Get-Item $($MyInvocation.MyCommand.Path)).DirectoryName
$parent_folder = Split-Path $this_script_path -Leaf
var1 and var2 is an Instance variables of ClassA. Create an Instance of ClassB and when calling the methodA it will check the methodA in Child class (ClassB) first, If methodA is not present in ClassB you need to invoke the ClassA by using the super() method which will get you all the methods implemented in ClassA. Now, you can access all the methods and attributes of ClassB.
class ClassA(object):
def __init__(self):
self.var1 = 1
self.var2 = 2
def methodA(self):
self.var1 = self.var1 + self.var2
return self.var1
class ClassB(ClassA):
def __init__(self):
super().__init__()
print("var1",self.var1)
print("var2",self.var2)
object1 = ClassB()
sum = object1.methodA()
print(sum)
You can try this code
Dictionary<string,string> AllFields = new Dictionary<string,string>();
string value = (AllFields.TryGetValue(key, out index) ? AllFields[key] : null);
If the key is not present, it simply returns a null value.
You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
conda create -n py37 -c anaconda anaconda=5.3
seems to be working.
The STAThreadAttribute
is essentially a requirement for the Windows message pump to communicate with COM components. Although core Windows Forms does not use COM, many components of the OS such as system dialogs do use this technology.
MSDN explains the reason in slightly more detail:
STAThreadAttribute indicates that the COM threading model for the application is single-threaded apartment. This attribute must be present on the entry point of any application that uses Windows Forms; if it is omitted, the Windows components might not work correctly. If the attribute is not present, the application uses the multithreaded apartment model, which is not supported for Windows Forms.
This blog post (Why is STAThread required?) also explains the requirement quite well. If you want a more in-depth view as to how the threading model works at the CLR level, see this MSDN Magazine article from June 2004 (Archived, Apr. 2009).

All of the other answers are either out of date or too much work where it doesn't need to be. Upload your .IPA file to diawi.com then either scan the QR-Code and install, or email the link to the device you want to install the app to, or type the shortened URL into your Safari browser and install that way.
I needed to get an app installed into an older iOS device today and this method took me less than 2 minutes to complete start to finish.

This is the Different Solution, Check if your Services are running correctly, if WAMP icon showing orange color, and 2 out of 3 services are running it's showing, then this solution will work . Root cause:
If in your system mysql was there, later you installed WAMP then again one MYSQL will install as WAMP package, default port for MYSQL is 3306 , So in both mysql the port will be 3306, which is a port conflict, So just change the port it will work fine. Steps to change the Port.
That worked for me in WPF application:
string configPath = Path.Combine(System.Environment.CurrentDirectory, "YourApplication.exe");
Configuration config = ConfigurationManager.OpenExeConfiguration(configPath);
config.AppSettings.Settings["currentLanguage"].Value = "En";
config.Save();
You don't have to have a method for that. You could create a property like this instead:
class SalesPerson
{
string firstName, lastName;
public string FirstName { get { return firstName; } set { firstName = value; } }
public string LastName { get { return lastName; } set { lastName = value; } }
public string FullName { get { return this.FirstName + " " + this.LastName; } }
}
The class could even be shortened to:
class SalesPerson
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string FullName {
get { return this.FirstName + " " + this.LastName; }
}
}
The property could then be accessed like any other property:
class Program
{
static void Main(string[] args)
{
SalesPerson x = new SalesPerson("John", "Doe");
Console.WriteLine(x.FullName); // Will print John Doe
}
}
check the err log on your /Applications/XAMPP/xamppfiles/var/mysql/ with filename like your_machine_name.local.err, if you find something like: "Attempted to open a previously opened tablespace. Previous tablespace ... uses space ID"
the following works for me:
edit file:
/Applications/XAMPP/xamppfiles/etc/my.cnf
find the [mysqld] section, add one line:
innodb_force_recovery = 1
then run
sudo /Applications/XAMPP/bin/mysql.server start
everything is ok again.
and then the last step:
edit the my.cnf again and remove the line you just added :
innodb_force_recovery = 1
and restart mysql again. Otherwise all your tables will be read only

public static void openKeyboard(final Activity activity, final EditText editText) {

}
public static void hideKeyboard(final Activity activity) {
final View view = activity.getCurrentFocus();
if (view != null) {
final InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
